I have been having some issues with a deformation calculator, the output is correct against my hand calculation, however I cannot figure how to have it output in mm,
%step bar internal force, internal stress and deformation calculator
syms FA1 FC2
format longEng
%A IS TOP POINT, B IS CENTRAL AND C IS BOTTOM
LAB=0.4;
LBC=0.5;
DAB=0.02;
DBC=0.06;
E=200e9;
%upwards +
FA= 10000;
FB= -30000;
eqn1= FA-FA1==0;
FAS = solve(eqn1,FA1)
eqn2= FA+FB-FC2 ==0;
FCS= solve(eqn2,FC2)
AAB= (((DAB)/2)^2)* pi;
ABC= (((DBC)/2)^2)* pi;
SAB= (FAS)/(AAB)
SBC= (FCS)/(ABC)
DEFAB= (FAS*LAB)/(E*AAB)
DEFBC= (FCS*LBC)/(E*ABC)
DEFTOT= DEFAB+DEFBC
%working but output is weird

In addition to @Torsten's answer, you can use vpa().
Also, note that changing display format is only applicable to numeric data types (and line spacing for that matter), whereas the output(s) you have obtained are symbolic numbers.
